Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis
The given question is incomplete. The complete question is:
Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis. Determine the mass of glucose (C6H1206) produced
Answer: 60.0 g of glucose
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
a) moles of [tex]CO_2[/tex]
[tex]\text{Number of moles}=\frac{88.0g}{44g/mol}=2.0moles[/tex]
b) moles of [tex]H_2O[/tex]
[tex]\text{Number of moles}=\frac{64.0g}{18g/mol}=3.5moles[/tex]
[tex]6CO_2+6H_2O\rightarrow C_{6}H_{12}O_6+6O_2[/tex]
According to stoichiometry :
6 moles of [tex]CO_2[/tex] require = 6 moles of [tex]H_2O[/tex]
Thus 2.0 moles of [tex]CO_2[/tex] require=[tex]\frac{6}{6}\times 2.0=2.0moles[/tex] of [tex]H_2O[/tex]
Thus [tex]CO_2[/tex] is the limiting reagent as it limits the formation of product.
As 6 moles of [tex]CO_2[/tex] give = 1 moles of glucose
Thus 2.0 moles of [tex]CO_2[/tex] give =[tex]\frac{1}{6}\times 2.0=0.33moles[/tex] of glucose
Mass of glucose = [tex]moles\times {\text {Molar mass}}=0.33moles\times 180g/mol=60g[/tex]
Thus 60.0 g of glucose will be produced from 88.0 g of carbon dioxide and 64.0 g of water
In green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis produces 60.0 g of glucose.
To calculate the moles, we use the equation:
Number of moles Given mass Molar mass a) moles ofNumber of moles = (88.0g)/(44g / mol) = 2.0mol*epsilonb) moles of H2ONumber of les = (64.0g)/(18g / mol) = 3.5molesAccording to stoichiometry6 moles of re = 6mol of H2OWhat is mole fraction ?Mole fraction is a unit of concentration, described to be same to the range of moles of a element divided via way of means of the entire range of moles of a solution.

Explanation:
2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂First we convert 9.90 g of Pb(NO₃)₂ into moles, using its molar mass:
9.90 g ÷ 331.2 g/mol = 0.0299 mol Pb(NO₃)₂Then we convert moles of Pb(NO₃)₂ into moles of PbO, using the stoichiometric coefficients:
0.0299 mol Pb(NO₃)₂ * [tex]\frac{2molPbO}{2molPb(NO_3)_2}[/tex] = 0.0299 mol PbONow we convert 0.0299 mol PbO into grams, using its molar mass:
0.0299 mol PbO * 223.2 g/mol = 6.67 g PbOSo 6.67 g is the theoretical yield. With that in mind we calculate the percent yield:
% yield = 5.51 / 6.67 * 100 % = 82.6%So the correct answer is option B.

Explanation:
Electron affinity is the energy change that results from adding an electron to a gaseous atom(Khan Academy). It is also defined as "the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion" (Wikipedia).
Electron affinity increases from left to right in the periodic table. However, the noble gases possess a complete outermost electron shell.
Hence, electron affinity can be raked from the most negative to the least negative for the three atoms as follows; Br>Ge>Kr
Glven 4.62 mol of sodium hydroxide, NaOH, how many grams are present?
According to the mole concept , there are 184.8 grams in 4.62 moles of sodium hydroxide.
What is a mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.Number of moles is given as, mass/ molar mass
∴mass=number of moles×molar mass
On substitution, mass= 4.62×40=184.8 g

This question is incomplete, the complete question is;
The purification of hydrogen gas by diffusion through a palladium sheet was discussed in Section 5.3. Compute the number of kilograms of hydrogen that pass per hour through a 5-mm-thick sheet of palladium having an area of 0.20 m² at 500C.
Assume a diffusion coefficient of 1.0 × 10⁻⁸ m²/s, that the concentrations at the high- and low-pressure sides of the plate are 2.4 and 0.6 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained
Answer:
the number of kilograms of hydrogen that pass per hour through is 2.592 × 10⁻³ kg
Explanation:
Given the data in the question;
thickness of sheet t = 5 mm
Area A = 0.20 m²
Temperature T = 500°C
diffusion coefficient ∝ = 1.0 × 10⁻⁸ m²/s
concentration high pressure side C[tex]_A[/tex] = 2.4
concentration low pressure side C[tex]_B[/tex] = 0.6 kg
from the question, we calculate the concentration gradient
dc/dx = (C[tex]_A[/tex] - C[tex]_B[/tex])/dt
so we substitute
dc/dx = (2.4 - 0.6) / ( - 5 × 10⁻³ )
dc/dx = -360
now, mass of hydrogen per hour that diffuse through a pd sheet
M = -∝AT(dc/dx)
where time t is 1 hour ( 3600 sec )
we substitute
M = -(1.0 × 10⁻⁸) × 0.20 × 3600 (-360)
M = 0.002592
M = 2.592 × 10⁻³ kg per one hour
Therefore, the number of kilograms of hydrogen that pass per hour through is 2.592 × 10⁻³ kg
The number of kilograms of hydrogen that pass per hour through a 5-mm-thick sheet of palladium having an area of 0.20 m² at 500°C is 2.592 × 10⁻³ kg.
Purification: It refers to the process of removing impurities or contaminants from a substance in order to make it cleaner, purer, or more refined. It also involves the elimination or reduction of unwanted substances or components that may be present in the original material.
According to the question, given data is:
Thickness of sheet t = 5 mm
Area A = 0.20 m²
Temperature T = 500°C
Diffusion coefficient ∝ = 1.0 × 10⁻⁸ m²/s
Concentration high pressure side [tex]C_A[/tex] = 2.4
Concentration low pressure side[tex]C_B[/tex]= 0.6 kg
from the question, we calculate the concentration gradient,
[tex]dc/dx = (C _A- C_B)/dt[/tex]
so, we substitute the values,
[tex]dc/dx[/tex] = (2.4 - 0.6)/ ( - 5 × 10⁻³)
[tex]dc/dx = -360[/tex]
Now, mass of hydrogen per hour that diffuse through a Palladium sheet,
M = -∝[tex]AT(dc/dx)[/tex]
where time t is 1 hour (3600 sec)
We substitute,
M = -(1.0 × 10⁻⁸) × 0.20 × 3600 (-360)
M = 0.002592
M = 2.592 × 10⁻³ kg per hour.
Therefore, the number of kilograms of hydrogen that pass per hour through a palladium sheet is approximately 2.592 × 10⁻³ kg.

Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the equation PV = C, where C is a constant. Suppose that at a certain instant the volume is 100 cm3, the pressure is 150 kPa, and the pressure is increasing at a rate of 30 kPa/min. At what rate is the volume decreasing at this instant?
Answer:
The volume is decreasing at a rate of 30 cm³/min.
Explanation:
From the question given above, pressure (P) and volume (V) are related by the following equation
PV = C
C => constant
If we make P the subject of the above, we shall have:
P = C/V
From the equation above (i.e P = C/V),
We can say that P is inversely proportional to V. This implies that as P is increasing, V will be decreasing and also, as P is decreasing, V will be increasing.
Considering the question given above, the pressure (P) is increasing at a rate of 30 kPa/min. Therefore, the volume will be decreasing at a rate of 30 cm³/min.
